Overhead Press Kneeling?

Overhead Press Kneeling?
—
I don’t have many of my client do overhead work in a standing position. At least not in the beginning.
—
One of the most common things I see in my clients is a lack of shoulder mobility. Because of this, a lot of people cannot reach overhead without some type of compensation from another area.
—
Typically I see clients flare their ribs high and arch their lower back. We want to avoid this as we want clients to be in a tall, lengthened spine position for all of their movements.
—
Getting into a kneeling or half kneeing position will typically help most people keep a lengthened spine will pressing overhead.
—
This can be even easier to stay lengthened when pressing unilaterally (one side at a time).

Have you tried pressing from a kneeling position?
